Dehumidifiers are great for pulling moisture from the air. A high-capacity one can handle big areas with a lot of moisture. For smaller spots, a standard room-size dehumidifier works well.

Besides dehumidifiers, desiccants like clay cat litter or calcium chloride absorb moisture. Put them close to damp walls to help dry them out faster.

Dealing with Insulation and Wall Coverings

If the walls have insulation or moisture barriers, these might have to be taken out. Certain insulation types like foil-backed or Styrofoam could need replacing. This is done to make sure the area dries properly.

The drying equipment runs non-stop. Professionals check the walls each day to ensure they are dry. This thorough process is vital for stopping water damage and mold.
